Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If an embossed sheet is glued to a polystyrene insulating sheet, then the sheet provides mechanical support and positioning for heating wires, but the adhesion is ineffective and the sheet may detach

Engineering Contradiction:
Improveadhesion strengthVSAvoidattachment reliability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent combines an embossed polymeric sheet with a foam insulating material to create a composite structure. The embossed sheet provides mechanical support and positioning features (protrusions and recesses) while the foam material provides insulation and additional bonding surface area, creating a composite material system that achieves both mechanical strength and thermal insulation properties effectively

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The embossed sheet features three-dimensional protrusions and recesses that create additional bonding surfaces in the vertical dimension. This dimensional transformation from a flat two-dimensional surface to a three-dimensional textured surface increases the effective adhesion area and mechanical interlocking capability between the sheet and the insulating material

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Strength

If the embossed sheet is molded together with the polystyrene sheet, then adhesion is improved, but the manufacturing process becomes complex and time-consuming

Engineering Contradiction:
Improveadhesion strengthVSAvoidmanufacturing process complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent separates the manufacturing of the embossed polymeric sheet from the insulating foam material. The embossed sheet is produced independently with its mechanical support features, then assembled with the foam insulating material. This segmentation allows each component to be optimized separately and simplifies the overall manufacturing process compared to simultaneous molding

Inventive Principle:
Principle #1Segmentation

3Loss of energy

If traditional insulating panels are used, then heat insulation is provided, but the panels have large thickness and poor adhesion

Engineering Contradiction:
Improveheat lossVSAvoidpanel thickness
Core Design Contradiction:
Loss of energyVSLength of stationary object

Solution Approach 1:

The combination of the embossed polymeric sheet and foam insulating material creates a composite panel structure that achieves superior thermal insulation performance with reduced thickness. The foam material provides high insulation efficiency while the embossed sheet adds minimal thickness while providing mechanical functionality

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the physical and structural parameters of the insulating panel by introducing the embossed sheet with specific protrusion and recess geometries. This structural parameter change enhances both the thermal insulation efficiency and the mechanical adhesion properties, allowing for thinner panel designs

Inventive Principle:
Principle #35Parameter changes

AI summary

A multilayer insulating panel is for the installation of an electric heating system having electric heating wires in a subfloor or in a wall of a building. The panel includes a main insulating layer including a first surface and a second opposite surface. A sheet made of polymeric material is operatively associated with one of the first or second surfaces. The sheet has a first face and a second opposite face and includes reliefs equally spaced apart on the first face to fix the electric heating wires on the first face in a reversible manner. A connection layer is fixed to the second face of the sheet. The connection layer is interposed between the second face of the sheet and one of the first surface or the second surface of the main layer following the association of the main insulating layer with the polymeric sheet.
